Removal and Replacement
1) Allow the ashes to burn completely and extinguish.
2) Push the ashes to the back of the rebox or remove all the ashes from the rebox.
3) Run a small prybar around the perimeter of the grate and the edge of the
ash pit to loosen the grate.
4) Lift out the broken grate.
5) Clean the edge of the ash pit in which the new grate will sit.
6) Install the new grate. Make sure to install the new grate with the narrow width

Optional Shaker Grates
Using Your Shaker Grate System
There are two main modes of operation for the Shaker Grate System.
These are Shake mode and Dump mode.
Shake mode is used mainly for daily use and consists of handle movement
with the stop in place. Moving the handle back and forth with the stop in
place allows for the breaking up and release of small pieces of klinker and ash
into the ashpan. This should be done daily or whenever coal is added to the
furnace. See gure 1.
The second mode is Dump mode and consists of handle movement with the
stop moved out of the way. Moving the handle back and forth, with the stop
out of the way, allows for full movement of the shaker grates as well as the
breaking up and release of large pieces of klinker into the ashpan. Dump
mode is needed when the klinker buildup on the shaker grates is such that it
causes restriction of airow to the re. See Figure 2.
During normal operation the shaker grates must be in a neutral position as
shown in Figure 3.
It is important that after using the shaker system in dump mode, all
klinker and ash is cleared out from the ashpan leaving NOTHING behind.
Anything left under the shaker grates can re-ignite causing damage to the
shaker grates.
